Datasheet

RFID systems operating on a frequency 125 kHz are still very widespread mainly for opening doors in apartment buildings, for recording of working time, and many other applications. These applications use a pre-encoded ID number on read-only 125 kHz chips for authentication.

There are multiple 125 kHz chips which work the same way and one of them is the TK4100, which is known as an inexpensive but reliable chip.

An RFID sticker with a 125 kHz chip TK4100 is thin, waterproof, with a diameter of 38 mm, and offers the possibility to use your RFID key under the mobile phone cover or it can be even glued to another card.

To use a sticker with your existing system, you have to enroll the sticker ID into your system and that is it.
